The present invention is adapted to be embodied in containers of various shapes and sizes and in containers intended to contain various substances. the formation of the container of various materials and combinations of materials. Throughout the following detailed disclosure I will describe a singletypical illustrative embodiment of the invention, it being understood that such disclosure is not to be construed as limiting or restricting the scope or range of the invention.

The improved container of the present invention illustrated in the .drawing includes, generally, a container body I0, ends or closure heads I! for closing the opposite ends of the body I8, and means I2 securing the heads II to the container body I8 and providing air tight and leak tight seals between the heads II and the body.

The body I 8 of the container is preferably tubular and in practice may constitute alength or portion of suitable tubular stock. The invention contemplates the formation of the container body III of paper, pressed paper, fiber or similar materials or combinations of such materials. The body III of my improved container may comprise a spirally wound strip of material of the general class mentioned or strips of such material which may .be doubly wound or spiralled in opposite directions or the body may be formed in any other manner. In the typical form of the invention illustrated the body I8 is cylindrical, it being understood that the body may be cone shaped or may be polygonal or oval in transverse cross section. The ends II of the tubular container body I 8 are preferably flat and preferably, though not necessarily, lie in planes at right angles to the longitudinal axis of the body. It is to be understood that the body I8 may be treated or coated either internallyor externally or both, to be moisture proof and impenetrable by the contents which it is intended to hold. The tubular container body I8 may be furnished to the user or packager with either one or both of the closure heads II loosely or partially secured thereto by the means I2. When the container body I8 is cone shaped a multiplicityof such bodies I8 may be supplied to the user or packager nested one within the other and each body I8 thus nested may'have a head II secured to or partially secured to its small end.

The ends or closure heads II are provided to close the opposite ends of the tubular container body I8. In practice the heads I I may be formed of paper, pressed paper, board, fiber or similar material provided with linings of paper or treated paper on either their external or internal surfaces,'or both. It is an important feature of the invention that the two heads II of the container may be identical in shape and construction and where the body I is cylindrical or of the same shape and dimensions atits opposite ends the two heads I I may be identical. a head II' provided with an outer covering 38 in the form of paper adapted to carry printed matter or the like and provided with a lining 3| of paper or the like on its inner surface which may be treated as required. The coverings 38 and the lining II may cover the entire inner and Further, the invention contemplates- Fig. 6 illustrates outer surfaces of the head II to have their peripheral portions engaged by the securing means I2 to be subsequently described.

The closure heads II are substantially disc shaped in their general configuration and their major portions are flat. If desired or necessary one or more circular corrugations I4 may be provided in the heads I I to render them more rigid. The peripheral portions of the heads II are shaped for engagement with the body III. In accordance with the invention an axially projecting flange I5 is provided on each head II. The flanges I5 are continuous and in the case illustrated where the body I 8 is cylindrical the flanges I5 are annular. The flanges I5 are intended to flt within the end portions of the body I8 and to bear outwardly against the internal surface of the body. It is preferred to make the flanges I5 outwardly flaring to tightly fit or engage in the end portions of the tubular body I8. Fig. 3 of the .drawing illustrates a flange I5 of a head I I" entering the tubular body I8 and illustrates the wedging cooperation of the flaring flange I5 with the internal surface of the body I8. As the heads II are initially formed they are provided with rims I6 projecting radially outwardly from the outer ends of the axial flanges I5 to be substantially parallel with the planes of the bodies of the heads II. The rims I6 are continuous or annular and are integral parts of the heads II. 'In this regard it is to be noted that the closure heads II of the container are simple inexpensive parts. In the particular case illustrated in the drawing the closure heads I I are both imperforate, it being understood that one or both heads II may have discharge openings or perforations for facilitating the removal or discharge of the contents from the container.

The means I2 for securing the heads II to the body I8 and for providing fluid tight and leak tight seals between the heads II and the body I8 is an important feature of the invention. Asthe two heads II may be identical the means I2 for securing the heads II in sealing relation to the body I0 maybe identical. This is important as it greatly facilitates the manufacture and assembling of the container and thus provides for general economy. As the means I2 for securing the two heads II to the container body I0 may beidentical I will proceed with a detailed description of the means I2 for securing one head II with the body I8, it being understood that such description may apply equally well to the means for securing the other head II to thebody I8.

'I'hemeans I2 for securing the head II to the container body I8 comprises an attaching or securing ring I8. As initially formed the ring I8 is substantially L-shaped in transverse cross section having a flange I 9 extending in the direction of its axis and a radially outwardly projecting flange 28. Thering I8 may be a simple integral member. The invention contemplates the formation of the ring I8 of metal or certain other materials such as suitable plastics that are capable of deformation or shaping when subjected to heat. In the simple embodiment of the invention illustrated in the drawing the ring I8 is relatively light and has smooth surfaces. The

axial flange I9 of the ring I8 is adaptedto bearagainst the inner surface of the head flange I5. Accordingly, the flange I9 is preferably slightly tapered or outwardly flared to properly seat in the flange I5. The'ring I8 is suitably curved or rounded where the flanges I9 and 20 join. The

radial flange 28 is adapted to cooperate with the rim I6 of the head II and with the wall of the body III as will be hereinafter described.

The rim I6 of the head II and the radial flange 20 of the ring I8 are adapted to be shaped or rolled to be locked together and to be brought into gripping and sealing cooperation one with the other and with the wall of the body I8. It may be preferred to roll the rim I6 and the flange 20 into locked or holding cooperation before applying the head II to the container body In so' that the head II and the ring I2 may be supplied to the user as a unit for quick application to the body III. The radial flange 20 of the ring I8 as initially formed projects some distance outwardly beyond the periphery of the rim I6. The projecting peripheral edge portion of the flange 20 is curled or rolled around the peripheral edge of the rim I6 to have a part 2| which engages the under or inner surface of the rim I6 and the engaging rim I6 and flange 2|] are rolled or curved to project in the general direction of the axis of the ring and head II.

The shape of the head II and the ring I2 following this initial rolling operation is illustrated in Fig. 3 of the drawing. It will be noted that the inner portions of the rim I6 and the flange 20 remain substantially normal to the axis of the ring I8 and substantially parallel with the body of the head. II and that the rolled in portion of the rim I6 and the engaging portion 22 of the ring flange 20 taper or are inclined outwardly.

The rolled in peripheral edge portion of the flange 28 forms the looking or gripping part 2I which tightly engages and seals with the rim I6 and tightly grips the peripheral edge portion of the rim I6 to securely connect the ring I8 with the head II. It will be observed that the outer curved portion 22 of the flange 28 and the part 2| receive the curved peripheral edge portion of the rim I6 to provide a strong positive connection between the ring I8 and the head II. The part 2| and the curved peripheral portion of the rim I6 are spaced outwardly from the flange I6 leaving an annular groove 23 which is adapted to receive the end portion of the body I as will be subsequently described. It will be apparent that curling or rolling of the ring flange 20 onto the rim I6 brings the flange I9 into tight contact with the head flange I and brings the portion 22 of the flange 28 in tight sealing contact with the outer surface of the rim I6. The inner end of the ring flange I9 may engage the outer surface of the head II to strengthen the assembly. The shaping or rolling of the ring I8 .as described above maybe accomplished by a suitable curling tool. The head II and the ring I8 secured together by the rolled together rim I6 and the ring flange 20 form a simple unit that may be supplied to the user or purchaser for application to the container body III or the head I I and the ring I8 may be supplied separately to be assembled when the container is sealed.

The closure head II with the rolled on ring I8 is adapted to be arranged on the end portion of the container body III. When the assembly of the head I and the ring I8 is arranged on the body In the head flange I5 enters the end of'the tubular body In and bears against its inner surface while the straight or unbent portion of the rim I6 seats on the end I3 of the body III. The space or groove 23 receives the end portion of the body III. The taper of the flange I5 provides for the effective wedging of the flange againstthe Internal surface of the body l0. With the head I I in the position where the straight portion of the rim I6 engages the end of the body III the part 2| and the curved portion of the rim I6 are at the outer surface or side of the body I0. Fig. 4 of the drawing illustrates the relationship between the parts just described.

Following the arrangement of the closure head II and the connecting ring I8 on the body III the part 22 of the ring flange 20 and the rim I6 are curled or rolled inwardly to secure the head II to the body and to provide a dependable seal between the body and head. In practice the flange part 22 and the rim I6 may be rolled in to finally or permanently seal the head II to the body In or they maybe only partially rolled inwardly to bear rather lightly against the wall of the body I0 so that the head Il may be removed without the use of an opening instrument. For the purpose of example it will be assumed that the head II is tightly or permanently secured to the body III in which case the part 22 of the ring flange 20 is rolled inwardly to bring the part 2| into tight gripping cooperation with the body III. This engagement or cooperation occurs at a point spaced below the end I3 of the body and the part 2| may be forced inwardly to the extent that it is recessed or partially embedded in the wall of the body III to have dependable locking cooperation with the body. Fig. 5 of the drawing illustrates the flnal position of the parts following the tightening in or rolling in of the part 22 of the flange 28.

The inward curling or rolling of the part 22 of the flange 20 of course results in corresponding inward curling or rolling of the rim I6 and the rim may have bearing and sealing cooperation with the outer surface of the body at the edge of the lock part 2|. The peripheral edge portion of the rim I6 is securely gripped between the parts 2| and 22 of the ring flange 20 to positively connect the head I I with the ring I8 and thus retain the flange I5 and the rim I6 of the head in proper bearing and sealing cooperation with the body. The flange I5 of the head is held in proper bearing and supporting engagement with the adjacent. wall portion of the body III by the ring flange I8 so that the body wall is reinforced when the ring flange 22 is rolled inwardly insuring the proper embedding of the part 2| in the body wall to provide the lock between the ring I8 and the body III. The forcing of the part 2| against the wall of the body I0 draws the rim I6 tightly against the outer surface and the end I3 of the body III and draws the ring flange I9 tightly against the internal surface of the body wall. The curled under part 2| of the ring I8 tightly clamps against and holds the peripheral part of the rim I6, dependably connecting the head II with the ring I8 and the body II). The crimping or rolling of the securing ring I8 as above described removes or substantially removes the taper from the end portion of the body wall and the flange I5 of the head II as illustrated in Fig. 5. The means I2 operating to connect the head II with the body III in the manner described above provides a dependable seal between the body III and the head II to prevent the leakage of the contents from the conmanufactu e because the two heads H and the means I! for securing the two heads to the body In may be identical. The means l2 secures the heads II to the body It! to provide a strong mechanical connection between the heads and the body and to positively prevent the leakage of the contents from the body. The gripping engagement of the part 2| with the rim I6 and the wall of the body I0 so securely connects the head H with the body II] that an inward pressure on the head H will cause complete failure of the head before the connection between the head and body fails or develops a leak. Further, the means [2 is such that a head II and an adjacent portion of the body In may be distorted or bent to an appreciable extent before a leak develops. The securing rings i2 are simple attractive parts that do not appreciably increase the bulk or size of the container and do not give the container the appearance of a tin can. A head I i and its securing ring i 2 may be removed from the body in as a unit to permit the removal of the contents or a portion of the contents from the container. This removal of the head II with its ring l2 may be accomplished with a suitable opening instrument. The head I I carrying the ring l8 may be replaced on the opened container to form an effective cover for the container. The means i2 is such that a head II may be removed in this manner without providing any sharp edges or parts and without excessive disflguration or mutilation of the container.
